SHINGLE CONSTRUCTION.

Application filed January 31, 1927. Serial No. 164,965.

My invention relates to shingle construction, and it consists in the combinations, constructions, and arrangements herein described and claimed.

5 In the past few .years roofing manufacturers have had considerable trouble from the curling of the so-called asphalt composition shingles. This curling may result from unequal expansion or contraction of the 1 shingle due to extremes of heat or cold, as well as to the action of the elements, such as the formation of ice or the force of the wind.

Various attempts have been madeto prevent the curling o f shingles of th1s type.

1 To this end certain shingles have been provided with a tongue which is arranged to enter a slot in anadjacent shingle. This has to an extent prevented the curling of the shingle, but the trouble is that the tongue,

itself, is liable to curl.

An object of my invention is to provide a composition shingle construction in which there is provided a tongue for locking the shingle in position and thereby preventing curling, while at the same time keeping the tongue, itself, in a locked positionand thus making a smoth roof structure.

Another object is to provide a composition shingle in which the tongues and slots are so arranged that they may be readily interlocked witha minimum of labor.

Other objects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

My invention is illustrated in the accom panying drawings, forming part of this application, in which Figure 1 is a plan'view of a shingle formed according to my invention,

Figure 2 is a plan view, showing a portion of the arrangement of a plurality of shingles on the roof, and

Figure 3 is an enlarged section along the line 33 of Fi re 2, showing the manner in which the shingles are locked.

In carrying out my invention, I make use of a composition shingle of a standard 'tgpe This may be the so-called asfphalt 50 s ingle which may consist of la ers o felt, asphalt and crushed slate or 0t ersuitable material, the invention residin material of which the shingle 1s made, but rather in the means for preventing the curling of the shingles.

In Figure 11 have shown a shingle of the '4. being provided near one corner of the shingles are inserted through the slots 5 not in the. are-virtually locked in preferred form. This consists of a body portion 1 having forwardly projecting portions 2 which are separated by'a recess 3, a recess shingle. The projectingportions 2 each has a pair of slots 5 and 6, respectively, which are disposed near the edge of the extensions 2 and are preferably located centrally of said extensions. Tongues 7 are punched from the shingle, extending inwardly from the inner edges of the recesses 3 and 4. These tongues, as it will be observed, are connected at their inner ends to the body portion of the shingle.

From the foregoing description of the various parts of the device, the operation thereof may be readily understood. In Figure 2 I have shown a number of the shingles as they have been applied to the roof. Assuming that the line w-w at the bottom of Figure 2 represents the edge of the roof, it

will be observed that I have cut oil the extensions 2 of the first row of shingles so that the shingles present a straight edge 8 0 along said roof edge. The shingles are laid end to end, and, as will be observed, the extensions are staggered so that they over.- lap.- The tongues 7 of the first row of and are then passed through the slots 6.

The next row of shingles is staggered likewise and their tongues 7 are passed through the slots 5 and 6 in the same manner. As each additional row of shingles is laid, the tongues are locked in the slots, and

it will be observed that the end of the tongue is always beneath the exposed part of the shingle. Of course each row of shingles is nailed before the next row .is laid on, this nailing being done at the points 8, which, as.

will be observed, are near the tongues7.. When the next adjacent row of shingles is laid, these nail holes of course are covered.

When the roof is finally shingled, it will present the appearance shown in Figure-2. It will be noted that the tongues 7 are firml secured and lie underneath the expose portion of the shingle. This forms a very substantial and thoroughly locked shingle covering. There are no exposed parts which are liable to curl because they place by the tongue and slot arrangement. I

I claim: 1. A composition roofing, series of rows ofashingles,

comprising a. each of said shingles having a body portion and spacedapart extensions, eac of said extensions having a pair of parallel slots disposed'centrally thereof, and said body portion being provided with a tongue at the edge of the space between said extensions, the extensions of the shingles of one row being staggered with respect to the extensions of the shingles of the other row and the tongues of one row of shingles being arranged to pass upwardly through certain of the parallel slots and downwardly through other of the parallel slots and to lie underneath and be covered by the extensions bearing the slots.

2. A composition roofing comprising a series of rows of shingles, each of said shingles having a body portion and spacedthe space between said extensions, the extensions of the shingles of one row being staggered with respect to the extensions of the shingles of the other .row and the tongues of one row of shingles being'arrangedto pass upwardly through certain of the parallel slots and downwardly through other of the parallel slots and to lie underneath andbe covered by the extensions bearing the slots,

whereby the tongues will lockinglyholdthe extensions in place. ABBOTT COBURN;
